We are loking to either link html text or enhance SAP search help so when staff our choosing GL accounts in PR's & PO's they can look at guidance on what should be charged to specific accounts. Can such user defined help text be added to matchcode or SAP standard help in any way, or links to html info be added?
I am curious as to what customers have created in this area
One way I can quickly think of to create the validation in transaction GGB0 with necessary prerequisits and checks.
In the message part of the validation define the message as information and in the long text of that message, you can maintain any thing you want in SE91.
Also remember to activate the validation in your application area.
